GPRS IP MODEM(DTU)

1.General

At recent years, 2.5 Generation mobile network (GPRS and CDMA 1x) has been widely used in many countries, it provides a wide range and reliable mobile data channel for business and industrial applications, especially in M2M field. Beijing Garefowl New-tech Co., Ltd. has developed an amazing and easy using GF-2008W/N GPRS DTU for those applications.

GF-2008W GPRS IP MODEM(DTU) is a plug and play communication Terminal for connecting any equipment with RS232/485 interface port to the Internet ,Including all the software and hardware components needs to transfer information remotely via the GPRS mobile networks .GF-2008W unleashes the power of M2M for a large range of equipment.

GF-2008W GPRS IP MODEM(DTU) is a new designed platform, supports GPRS network. There are many improvements, such as industrial class pluggable terminal, embedded RTOS and embedded TCP/IP stack driving by AT+I command interface and Enhanced EMI design.

2.Overview

GF-2008W GPRS IP MODEM(DTU) enables various kinds of legacy devices with serial port to communicate over GPRS network and the Internet easily and freely. It not only works as a GPRS Modem, but also can construct a smooth "GPRS Data Tunnel" between Host End and Remote End, ensuring an efficient communication for data transmission and remote device management. With 1 selectable RS-232/TTL/485 serial port, GF-2008 GPRS DTU is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry. Meanwhile, it is supplied with simple software interface that streamline application development process, freeing system integrators from dealing with complex communication protocols of GPRS and the Internet. Users do not need to change the existing system, saving cost and time for field maintenance, and making it a perfect solution for data transmission.

3.GF-2008W GPRS IP MODEM(DTU) Features

1) Transparent data transmission

GF-2008W GPRS IP MODEM(DTU) provides transparent data transmission (RS232 or RS485 interface) for machine to machine connectivity.

2) Non host support

Normally, GPRS Modem can be connected to a PC, and then dial an access number manually; it utilizes PC's OS resources to finish the data transmission and protocol conversion. GF-2008W GPRS IP MODEM(DTU) is a powerful communication terminal in witch the microprocessor, TCP/IP stack and application software are embedded ; it works automatically without host PC.

3) Point to point, and multi-point to point data transmission

GF-2008W GPRS IP MODEM(DTU) can be configured working in point to point, multi-point to point and center to multipoint network frames .

4) Always online

GF-2008W GPRS IP MODEM(DTU) will automatically attach to GPRS network when the power is on, and then set up one up to ten sockets to the center server..

5) cost saving toll

GF-2008W GPRS IP MODEM(DTU) can work always online state, and only be charged when data transmitted.

6) High speed

Maximum GPRS bandwidth can be 171.2Kb/s, only 40~100Kb/s can be reached at actual application.

7) Simple and flexible to use

GF-2008W GPRS IP MODEM(DTU) is a powerful and easy to used device. It is easy to build your own private mobile data network at anywhere.
